Most cells do not continuously divide. These cells enter the G0 phase of the cell cycle after dividing and do not begin diving again until stimulated to do so. Growth factors, nutrients, etc. are required to make these start dividing again. When these cells are needed, the appropriate growth factors will be introduced, and then they will begin dividing again.
Some cells do continuously divide, such as epithelial (skin) cells.
The cells that keep on dividing, even though they are not supposed to, are cancer cells. They eat up all your nutrients and form tumors etc.
No. Different cells grow and divide in response to external/internal stimuli, which most often is not at the same time.
yes.
Yes.
A bacterium will undergo a splitting process called binary fission about 20 minutes after it is first formed. This time varies depending on the type of bacteria.it depends on the generation time of that particular bacteriumMany divide around six times a day.
Cells multiply, doubling their population every time they do via cytokinesis. This causes growth.
The larger the cell becomes the more trouble the cell has moving enough nutrients and wastes across the membrane because the membrane can't expand wide enough to fit the inside volume. Like on a balloon, you blow it up too big and it pops because the outer surface can't support the inside contents.
The number of cells in an organism constantly changes. Cells die and are replaced by new cells all the time. As I type, cells on my fingertips die, fall off and new cells replace them. There are far too many cells to count in any organism, and they are constantly changing. Here's an interesting fact- if one of the cells on the tip of your nose was the size of a football pitch, your head would be the same size (roughly) as the world!
For the speed of a single pedestrian, measure the time it takes him/her to walk a set distance (for example 10 meters) and divide the distance by the time. For the average speed of a pedestrian find a large number of people and measure the speed of each person and find the average by summing all the speeds and dividing by the number of people who took the test.
They don't. Some grow and divide all the time (skin cells) and some never do (nerve cells) and some only at times when needed.
Well they really dont divide at the same time
No. Some cells are larger than others, therefor it will take a longer time for the cells to divide.

No, cells undergoing meiosis take longer time than those undergoing mitosis
the cells which must help for a human's growth undergo it, in other words most do
Labile cells (the kinds of cells that can divide throughout their lifetime) normally do so within the organ they constitute. Some examples of labile cells are skin cells, cells of the gastrointestinal tract, and blood cells; however, blood cells divide in the bone marrow and lymphocytes divide in the lymph nodes. Other kinds of cells in the body are either stable cells (that do not normally divide--this includes nerve cells) and permanent cells (that do not have the ability to divide.)
The only answer that there is available is no
No to cannot live without cell division because our cells need to divide to make us grow. Also we need cell division to survive because our cells only live for a limited amount of time, so if our cells don't divide then the cells will just die and we won't survive.
cells divide into 2 at a time
DNA ultimately controls all the cell's functions, so it is necessary to have it in all your cells. Every time your cells divide so that you can grow or repair your body, the DNA needs to duplicate so that it can be in each of your cells.
They divide, it takes some long time.
